DURANGO, Colo. (CBS4)– Now that the remains of Dylan Redwine have been found the question remains: how did he get there? Dylan’s father told CBS4 that his ex-wife has called him a killer.

“I was standing outside and her vehicle passed by and turned around in the driveway in front of my house and as she was passing by she muttered out the window, ‘Murderer,'” said Mark Redwine.

Dylan had been missing since Nov. 19, a day after arriving at his father’s Vallecito home for a court-ordered visit during Thanksgiving break. The boy was living with his mother and brother, Cory, in the Colorado Springs area.

His father, Mark Redwine, says he last saw Dylan asleep when he left home early to do some errands. He reported the boy missing that afternoon.

Redwine’s parents have blamed each other for his disappearance and did so publicly on the CBS show Dr. Phil.

In 2005 Dylan’s mother, Elaine, requested a temporary restraining order against Mark, claiming he posed a “credible threat” that an imminent danger existed for the life and health of Dylan and Cory.

The La Plata County Sheriff’s Office announced Thursday afternoon that human remains found have been identified as Dylan’s.

A variety of items including bones were collected during a five-day search of Middle Mountain Road. Middle Mountain is located north and within sight of Vallecito Lake, near Dylan’s father’s house. The search area ranged from 8,000 to 11,000 feet altitude and consists of deep canyons and dense forest.

Mark said others have accused him of playing a role in Dylan’s disappearance.

“Obviously I love Dylan very much and he’s a very important aspect of my life and always has been. I would never do anything to hurt him,” said Mark.

Dan Bender with the La Plata County Sheriff’s Office said the subdivision where Dylan was staying with his father is visible from Middle Mountain across the valley.

“We’re pursuing this as a criminal investigation and not an accident,” said Bender.

Dylan’s older brother Cory believes his own father may have the much-needed answers to the mystery.

“I believe that Mark is, Mark is holding the key,” said Cory. “We strongly believe that the last person to see Dylan knows the truth.”

Mark said he wants to see where his son’s remains were found and honor him with respect.
